the short shofter did not come woth any instructions so i've been browsing and found the 900 installation guide. in the directions it says to loosen the bolt connecting the gear shift linkage to the gear box and then it says to loosen and remove the shifter assembly. in doing this, the whole linkage arm is removed with it. it it ok to remove the linkage arm from the gear box? will it just slide back in when i try to install it again? thanks.
